This application is a continuation of and claims priority under 35 U.S.C. §365 and 35 U.S.C. §119 to PCT Application No. PCT/CN2014/077146, filed on May 9, 2014, which claims the benefit of priority to a Chinese Patent Application No. 201310412690.7, filed on Sep. 11, 2013, both of which are incorporated herein by reference in their entireties.

FIELD OF THE TECHNOLOGY

The present disclosure generally relates to internet field, and more particularly, to a method, apparatus and system for providing network access to a smart device.

BACKGROUND

More and more smart devices such as smart lights, smart fans and smart refrigerators are involved in our life and work. Terminals such as smart cell phones, tablet PC and laptop can be configured to control the smart devices to achieve various function with high efficiency.

It is necessary for the smart devices to set WIFI (Wireless Fidelity) password to access network while the smart devices achieve various function with high efficiency. Current methods for providing wireless network access to smart devices are carried out through configuring WPS encryption with a single key for wireless router, such that the access of the smart devices to the network is achieved. Both the smart devices and the wireless router must be subjected to WPS authentication, which is necessary for configuring WPS encryption with a single key, and both of them should be respectively provided with one button. For the smart devices with input screen, the said button may be a virtual button shown in the screen. For the smart devices without input screen such as intelligent light or intelligent fans, a solid button should be provided or mounted on these smart devices. The users press the button on the smart devices and then press the button on the wireless router to allow the smart devices to access network after selecting the WPS access point for the smart devices.

Thus, for most smart devices and wireless routers without input screen, they should be provided with a solid button. The network access is achieved through pressing this button. However, the design and configuration of the button is limited. For example, it is very difficult or unaesthetic to mount a button on some smart devices such as intelligent glasses. Therefore, the application of current method for wireless network access is limited. Additionally, the smart devices such as intelligent lights and intelligent conditioners are often mounted on the higher place or the place not easily reached by user. Therefore, current methods for wireless network access lack feasibility and versatility.

The terminal 120 may be a cell phone, a tablet PC, an electronic book reader, MP3 (Moving Picture Experts Group Audio Layer III) player, MP4 (Moving Picture Experts Group Audio Layer IV) player, laptop and desktop PC and the like. Alternatively, the terminal 120 can be just a software application running on the aforementioned electronic devices.

Each wireless access point 160 and each smart device 180 have their own identifications. The identification is the identifier for identifying the wireless access point 160 or the smart device 180. In one embodiment, the terminal 120 is provided with an application program for reading and identifying the identifier of the wireless access point 160 and the smart device 180. In one embodiment, an application program may generate identifier of terminal 120 for distinguishing various terminal users. In some embodiments, a terminal identifier can also be a user account associated with a software application, preferably when the terminal 120 is a software application. One terminal 120 may include a number of terminal users and the identifier is different from each other. The identifier can be a string. For example, the terminal 120 can be a cell phone with WeChat application program, a mobile text and voice messaging communication service developed by Tencent in China, and a WeChat account of a user is “117417255”, and thus the account “117417255” will be the identifier of the terminal 120.

The terminal 120 can be connected with the server 140 via either wireless network or wired network.

The server 140 may be one server or server cluster consisting of several servers or a cloud computing service center. The server 140 saves the identifications of each wireless access point 160 and each smart device 180. In one embodiment, the server 140 also saves keys of each wireless access point 160 and each smart device 180.

SSID is known as wireless network channel. In some embodiments, SSID1 is a normal wireless network channel, which may be encrypted. Any smart device is linked to network via the normal SSID1 through verifying the access password. In some embodiments of the present disclosure, SSID1 refers to a network provided by the wireless access point. SSID2 can be a special wireless network channel without encrypting, which is used for the smart device 180 to obtain network access authentication information, such as access password, of the wireless access point. In some embodiments of the present disclosure, SSID2 refers to a preset channel of the wireless access point. In these embodiments, the access password of the wireless access point can be the access password of SSID1. In some embodiments, a manufacturer can set the two SSIDs of wireless access point 160 according to properties and requirements of these two SSIDs. Alternatively, these two SSIDs can also be set via some specific open source router ROM (Read-Only Memory) firmware by a user, such as a third party firmware known as DD-WRT that can be configured to set some functions of a wireless router.

Meanwhile, in some embodiments, the wireless access point 160 need install a process which can be linked to the server 140 and can also monitor and communicate with the smart device 180. The process can also read the network access authentication information of the wireless access point.

The smart device 180 may be intelligent lights, fans, curtains, conditioners, electric cookers, refrigerators, watches, glasses and shoes and the like. It should be noted that the smart device 180 for the present disclosure does not require a display or input in it. The fields which the smart devices are involved in and the types of the smart devices are increasing with the development of technology. In some embodiments, the smart device includes a machine-readable code, either on the smart device, on or in the package of the smart device 180. In some embodiments, a machine-readable code can also be obtained online through the manufacturer's website. The machine-readable code comprises the identification information and key of the smart device 180. A user can scan machine-readable codes using the terminal, such as a smart phone having a camera, to obtain the identification identifying the smart device 180. The machine-readable codes include, but are not limited to, Universal Product Codes (UPC), quick response (QR) codes, Qode, MaxiCode, Data Matrix, PDF417, SPARQCode or the like. A machine-readable code can either be a 2-dimensional code, a 3-dimensional code or a multi-dimensional code. In some embodiments, the identification and key of each smart device 180 can also be saved in the chip thereof.

FIG. 3 shows a flow chart of the method for network access according to another embodiment of the present disclosure. This embodiment is illustratively described in terms of applying the method for network access to the environment as shown in FIG. 1. The method for network access includes:

step 301, receiving, by a server comprising a processor and a non-transitory storage medium, a first identification identifying a wireless access point and a first terminal identifier;

Each wireless access point and each smart device have their own identification and the identification is the identifier for indicating the wireless access point and smart device, which may comprise information relating to device type and device ID and carried by a machine-readable code. The machine-readable codes include, but are not limited to, bar code, Universal Product Codes (UPC), quick response (QR) codes, Qode, MaxiCode, Data Matrix, PDF417, SPARQCode, words, NFC label or the like. The machine-readable code can either be a 2-dimensional code, a 3-dimensional code or a multi-dimensional code. A device type can be a random string, for example “tplink-tlwr2042n” and the device ID may also be a string such as “ed2c3sed2”. The identification of wireless access point and smart device can be set by manufacturers and the identifications of any two devices are different from each other.

For the convenience of access of the smart device to the network provided by the wireless access point, the identifications of each smart device and each wireless access point, i.e. the machine-readable code, can be a label on the surface of the device, alternatively, it can also be printed on a paper or card to put into the package of the device, or can also be printed on the package, and so on. The terminal is provided with an application program for reading or obtaining the identifications of the wireless access point and smart device.

The terminal is connected to the server via wireless or wired network to transmit information. The first terminal identifier can identify the terminal that obtained the identification of the wireless access point. In some embodiment, the first terminal identifier can also identify a user account for the software program running in the terminal.

step 302, receiving, by the server, a second identification identifying a smart device and a second terminal identifier;

step 303, associating, by the server, the wireless access point with the smart device if the first terminal identifier corresponds to the second terminal identifier; The identifications of each wireless access point and each smart device may have been already registered in the server, that is to say, the server may restore the identifications of each wireless access point and each smart device. After the server receives the identifications of wireless access point and smart device sent from the terminal, in some embodiments, the server detects whether the identifications of wireless access point and smart device have been already registered or not, if registered, the identification of the wireless access point is associated, by the server, with the identification of the smart device.

step 304, sending, by the server, the second identification for the associated smart device to the wireless access point; wherein a certain process which can be connected and communicated with the server is installed on the wireless access point; after the server sends the associated identification of the smart device to the wireless access point, the wireless access point can determine the smart device which needs to connect with itself.

Correspondingly, the wireless access point receives the identification of the smart device sent from the server.

step 305, the wireless access point provides network access authentication information to the smart device; wherein the wireless access point directly or indirectly sends the network access authentication information, such as access password thereof, to the smart device through preset channel after determining the smart device connecting with it. In a direct way, the wireless access point sends the access password to the smart device by the wireless access point itself. In an indirect way, to the wireless access point sends the access password to the server and then the server forwards it to the smart device.

Correspondingly, the smart device receives the access password of the wireless access point that is directly or indirectly sent from the wireless access point through preset channel.

step 306, the smart device accesses the network provided by the wireless access point with the network access authentication information.

In some embodiments, each wireless access point may have two SSIDs (service set identifiers), assuming SSID1 and SSID2. For example, in some embodiment, SSID is known as wireless network channel. SSID1 may be a normal wireless network channel which can be encrypted. Any smart device accesses network via this normal SSID1 in the case that the access password is verified. In present example, SSID1 is referred as a network provide by wireless access point. In some embodiments, SSID2 can be a special wireless network channel without encrypting and is merely configured to obtain the access password of the wireless access point by the smart device. In the present example, SSID2 is referred as preset channel provided by wireless access point. The access password of the wireless access point is the password of SSID1. The smart device receives the access password and then links to SSID1, thereby accessing internet.

In sum, according to the method for access network provided by the present embodiment, the access of the smart device 180 to the network is achieved by obtaining the identifications of the smart device 180 and wireless access point via the terminal 120 and then sending them to the server 140, and achieving the connection between the smart device 180 and wireless access point 160 via the server. Thus, the present disclosure can solve the problem relating to the limitation to the application of the methods for wireless network access and lack of feasibility and versatility and provide a simplified method for linking the smart device to network with enhanced feasibility and versatility.

FIG. 4 shows a flow chart of the method for network access according to another embodiment of the present disclosure. This embodiment is also illustratively described in terms of applying the method for network access to the environment as shown in FIG. 1. As an exemplary example based on the one shown in FIG. 3, the method for network access provided in the present embodiment includes:

step 401, receiving, by a server comprising a processor and a non-transitory storage medium, a first identification identifying a wireless access point and a first terminal identifier; For the convenience of access of the smart device to the network provided by the wireless access point, the identifications of each smart device and each wireless access point, i.e. the machine-readable code, can be a label on the surface of the device, alternatively, it can also be printed on a paper or card to put into the package of the device, or can also be printed on the package, and so on. The machine-readable codes include, but are not limited to, Universal Product Codes (UPC), quick response (QR) codes, Qode, MaxiCode, Data Matrix, PDF417, SPARQCode or the like. A machine-readable code can either be a 2-dimensional code, a 3-dimensional code or a multi-dimensional code. The terminal is provided with an application program for reading or obtaining the identifications of the wireless access point and smart device.

The terminal is connected to the server via wireless or wired network to transmit information. The first terminal identifier can identify the terminal that obtained the identification of the wireless access point. In some embodiment, the first terminal identifier can also identify a user account for the software program running in the terminal.

In some embodiments, this step may be divided into first implementation without associating and the second implementation with associating on the basis whether the terminal is pre-bound with wireless access point. In the first implementation, this step includes following two sub-steps:

firstly, obtaining the first identification provided by the wireless access point via first predetermined way at the first moment;

secondly, obtaining the second identification provided by the smart device via second predetermined way at the second moment, wherein the time period from the first moment to the second moment is less than the predetermined threshold value.

The terminal predetermines the threshold value between the second moment and the first moment. The obtaining, in some embodiments, by reading, is effective provided that the time period from the moment at which reading the first identification provided by the wireless access point to that at which obtaining the second identification provided by the smart device is less than the threshold value, otherwise the reading is regarded as ineffective or failure due to time out and the user needs to perform reading operation again. For example, under the condition that the preset minimal threshold value is 20 seconds, a certain user reads the first identification provided by the wireless access point at 9:30:00. If the user reads the second identification provided by the smart device within 9:30:20 (not including 9:30:20), the reading is effective. Otherwise, the reading is regarded as ineffective or failure due to time out.

In some embodiments, in the second implementation, this step may include following sub-steps:

obtaining the first identification provided by the wireless access point through the first predetermined way at the third moment;

obtaining the second identification provided by the smart device through the second predetermined way at the fourth moment.

In comparison with the first implementation, the time period from the moment at which reading the first identification provided by the wireless access point to that at which reading the second identification provided by the smart device is not defined in the second implementation. For example, a certain user reads the identification provided by wireless access point at 9:30:00, he/she could read identification provided by the smart device at any time such as at 10:30:00, even at 9:30:00 next day.

In the first and the second implementations, the first predetermined way includes: scanning the machine-readable code on the wireless access point, and/or communicating with wireless access point through wireless Near Field Communication technologies (NFC). In some embodiments, the second predetermined way may include: scanning the machine-readable code on the smart device, and/or communicating with smart device through wireless Near Field Communication technologies (NFC).

step 402, receiving, by the server, a second identification identifying a smart device and a second terminal identifier, wherein the terminal and the server can be connected through wireless or wired network to transmit information.

In some embodiments, corresponding to the first implementation in step 401, this step may include:

sending the first identifications of the wireless access point and the second smart device from the terminal to the server simultaneously.

When the time period from the moment at which obtaining the first identification provided by the wireless access point to that at which obtaining the second identification provided by the smart device is less than the predetermined threshold, the terminal effectively obtains the identifications provided by the wireless access point and smart device and then sends the identifications of the wireless access point and the smart device to the server simultaneously.

Correspondingly, the server simultaneously receives the identifications of the wireless access point and smart device sent from the terminal.

Wherein the first identification of the wireless access point is obtained from the wireless access point by the terminal through the first predetermined way at the first moment, and the second identification of the smart device is obtained from the smart device by the terminal through the second predetermined way at the second moment.

In some embodiments, corresponding to the second implementation in step 401, this step may include following two sub-steps:

firstly, sending the first identification of the wireless access point and a first terminal identifier of the terminal from the terminal to the server;

In some embodiments, the terminal identifier is configured to distinguish various terminal users in the terminal, and one terminal may contain a number of terminal users but the identifiers can be varied depending on various terminal users, the identifier is typically a string.

Correspondingly, the server receives the first identification of the wireless access point and the first terminal identifier of the terminal sent from the terminal, and generates the binding relationship between the identification of the wireless access point and the terminal identifier of the terminal from the server, wherein the first identification of the wireless access point is obtained from the wireless access point through the first predetermined way by the terminal at the third moment.

secondly, sending the second identification of the smart device and the second terminal identifier of the terminal from the terminal to the server;

Correspondingly, the server receives the second identification of the smart device and the second terminal identifier of the terminal sent from the terminal, wherein the identification of the smart device is obtained from the smart device through the second predetermined way by the terminal at the fourth moment. In this implementation, even though the interval between the time points for performing the aforesaid two sub-steps is long, the present step is effective due to pre-binding of the terminal and the wireless access point. As mentioned in step 401, even if the interval between the two time points is one day or even longer, the implementation can also be performed.

step 403, associating, by the server, the wireless access point with the smart device if the first terminal identifier corresponds to the second terminal identifier. In some embodiments, the identifications of each wireless access point and each smart device may have been already registered in the server, that is to say, the server saved the identifications of each wireless access point and each smart device. In some embodiments, after the server receives the identifications of wireless access point and smart device sent from the terminal, the server detects whether the identifications of wireless access point and smart device have been already registered or not, if registered, the identification of the wireless access point is associated with the identification of the smart device.

In some embodiments, corresponding to the first implementation in step 401, the server may directly associate the identification of the wireless access point with the one of the smart device because the server receives the identifications of the wireless access point and the smart device simultaneously sent from the terminal.

In some embodiments, corresponding to the second embodiment in step 401, the server initially receives the identification of the wireless access point and the identifier of the terminal sent from the terminal and generates the binding relationship between the identification of the wireless access point and the identifier of the terminal. Thereafter the server receives the identification of the smart device and the identifier of the terminal sent from the terminal. The server finds the identification of the wireless access point bound with terminal according to the identifier of the terminal and the binding relationship, and then associates the found identification of the wireless access point with the one of the smart device.

It is appreciated that the correlation, i.e. association, is merely used by server to determine which smart device and which wireless access point are connected together, but cannot indicate that the smart device is connected with the wireless access point via wireless or wired network.

step 404, sending identification of the wireless access point to the server from the wireless access point;

In some embodiments, for the reason of security, the server needs to verify the identification of the wireless access point before sending the associated identification of the smart device to the wireless access point. The identity of the wireless access point may be verified by checking the identification of the wireless access point by the server. The wireless access point is provided with a certain process which can be connected to the server and communicated with the server. The wireless access point sends its identification to the server.

Correspondingly, the server receives the identification of the wireless access point sent from the wireless access point.

step 405, verifying, by the server, whether the wireless access point is pre-registered based on the first identification;

In some embodiments, each wireless access point may be pre-registered in the server. For example, the server may pre-store the identification of each wireless access point. The server verifies the identification of the wireless access point by detecting whether the identification of the wireless access point has been registered and saved in the server.

step 406, if the wireless access point is pre-registered, sending the associated identification for the smart device to the wireless access point;

If the detection result is that the wireless access point was pre-registered, the authentication of the wireless access point performed by the server is successful and the server informs the wireless access point of the identification of the smart device.

It is appreciated that steps 404 to 406 are often performed after steps 401 to 403. However, steps 404 to 406 could be performed with steps 401 to 403 simultaneously. Steps 404 to 406 can also be performed before steps 401 to 403. The present embodiment illustratively describe the condition that steps 404 to 406 are performed after steps 401 to 403, but not limited to this.

step 407, sending the associated identification for the smart device to the wireless access point;

In some embodiments, after the server sends the associated identification of the smart device to the wireless access point, the wireless access point may determine the smart device which needs to connect with itself.

Accordingly, the wireless access point receives the identification of the smart device sent from the server.

step 408, establishing, by the smart device, a connection with the wireless access point.

In some embodiments, this step includes following two sub-steps:

firstly, obtaining the gateway address of the wireless access point through preset channel by using the predetermined way by the smart device;

In some embodiments, the smart device also needs to know the gateway address of the wireless access point to connect with the wireless access point when it scans and obtains the preset channel such as SSID2 in the wireless access point. Meanwhile, the smart device needs to obtain the gateway address of the wireless access point via a predetermined way which includes:

obtaining through running the interface of underlying application of the smart device;

in some embodiments, the interface of the underlying application can be API (Application Programming Interface), which is predefined functions and provides the capability of visiting a set of routine with the application or developer, without visiting source code or understanding the details of the internal mechanism, and wherein the chip of the smart device will carry corresponding SDK (Software Development Kit), some of which possess such functional API.

or obtaining through parsing the host name of the wireless access point by a domain name server;

in some embodiments, the IP (Internet Protocol) address obtained through parsing IP address of the host name of the wireless access point by a domain name server is the gateway address of the wireless access point;

or obtaining through broadcast user datagram protocol UDP packet; in some embodiments, the gateway address of the wireless access point can be obtained from the returned packet which is received from the gateway of the wireless access point through sending the broadcast UDP.

Secondly, connecting the smart device with the wireless access point according to the gateway address of the wireless access point;

In some embodiments, each wireless access point may have two SSIDs (service set identifiers), assuming SSID1 and SSID2. Exemplary, SSID is known as wireless network channel. SSID1 can be a normal wireless network channel which may be encrypted. Any smart device links to network via this normal SSID1 in the case that the access password is verified. In some embodiments, SSID1 is referred as a network provided by wireless access point. SSID2 can be a special wireless network channel without being encrypted and is merely configured to obtain the access password of the wireless access point. In the present embodiments, SSID2 is referred as a preset channel provided by wireless access point. The access password of the wireless access point is the password of SSID1. The smart device receives the access password and then links to SSID1, thereby linking to network.

In the present embodiment, the smart device is connected with the wireless access point via SSID2 which refers to preset channel provided by wireless access point after obtaining the gateway address of the wireless access point.

step 409, receiving, by the wireless access point, identification of the smart device from the smart device; in some embodiments, the wireless access point can verify the identification of the smart device before sending the access password to the smart device that may make wireless access point confirm its own identity through the identification of the smart device itself.

It is appreciated that steps 408 and 409 are often performed with step 407 simultaneously, but steps 408 and 409 may be performed before step 407. Steps 408 and 409 may also be performed after step 407. The present example merely describes the condition that steps 408 and 409 are performed after step 407, but not limited to this.

step 410, determining, by the wireless access point, if the identification from the smart device corresponds to the second identification received from the server, in some embodiments, the wireless access point can verify the identity of the smart device through comparing the identification of the smart device received through the preset channel and the identification of the smart device received from the server.

In some embodiments, in the various examples, the verification performed in this step may be more complicated. Additionally, considering the security, the information transfer among the smart device, wireless access point and the server will encrypt some information before sending.

step 411, if the identification from the smart device corresponds to the second identification received from the server, sending, by the wireless access point, network access authentication information required by the wires access point to the smart device through the connection, in some embodiments, the wireless access point sends its access password to the smart device through the preset channel after the verification for the identity of the intelligent performed by the wireless access point device is successful.

Correspondingly, the smart device receives the access password of the wireless access point sent from the wireless access point through the preset channel.

step 412, the smart device accesses a network provided by the wireless access point with the network access authentication information.

In some embodiments, the network provided by the wireless network point may be SSID1 that is a normal wireless network name and the network may be encrypted. Any smart device links to network via this normal SSID1 in the case that the access password is verified. After receiving the access password, the smart device is connected with SSID1 to link to the network.

It is appreciated that considering the security of information transfer among the smart device, wireless access point and server, the key may be pre-saved in the server by the smart device and wireless access point and the information to be sent can be encrypted via the key. The encryption method may be AES (Advanced Encryption Standard) symmetric encryption or other encryption.

It is also appreciated that considering the security and conciseness of information transfer among the smart device, wireless access point and server, the information to be delivered can be message-digested before sending. Message-digest algorithm may be md5 (Message-Digest Algorithm 5), or other digest algorithms such as md4, md3 or md2.

In sum, according to the method for access network provided by the present embodiment, the access of the smart device 180 to the network is achieved by obtaining the identifications of the smart device 180 and wireless access point via the terminal 120 and then sending them to the server 140, and achieving the connection between the smart device 180 and wireless access point 160 via the server. Thus, the present disclosure can solve the problem relating to the limitation to the application of the methods for wireless network access and lack of feasibility and versatility and provide a simplified method for linking the smart device to network with enhanced feasibility and versatility.

SSID1 can be a normal wireless network channel which may be encrypted. Any smart device links to network via this normal SSID1 in the case that the access password is verified. In some embodiments, SSID1 is referred as a network provided by wireless access point. SSID2 can be a special wireless network channel without being encrypted and is merely configured to obtain the access password of the wireless access point. In the present embodiments, SSID2 is referred as a preset channel provided by wireless access point. The access password of the wireless access point is the password of SSID1. The smart device receives the access password and then links to SSID1, thereby linking to network.

In the present embodiment, the smart device is connected with the wireless access point through SSID2 referred as preset channel provided by wireless access point after obtaining the gateway address of the wireless access point.

step 509, sending the identification of the smart device by the smart device to the wireless access point through the established connection;

wherein the wireless access point verifies the identification of the smart device via the server before sending the access password to the smart device that may allow the wireless access point confirm its identity through its own identification.

It is appreciated that steps 508 and 509 are often performed with step 507 simultaneously, but steps 508 and 509 may be performed before step 507. Steps 508 and 509 may be performed after step 507. The present example merely describes the condition that steps 508 and 509 are performed after step 507, but not limited to this.

step 510, forwarding, by the wireless access point, the identification of the smart device to the server, wherein the identity of the smart device can be verified by the wireless access point via the server.

And md5 of “random1” is encrypted in a manner of AES encryption to obtain AES for md5 of “random1”. Similarly, the second random string “random2” is decrypted by the smart device and then subjected to md5 processing, thereby obtaining md5 of “random2”. And md5 of “random2” is encrypted in a manner of AES encryption to obtain AES for md5 of “random2”.

Message-digest algorithms may be md5 (Message-Digest Algorithm 5), or other digest algorithms such as md4, md3 or md2.

In sum, according to the method for access network provided by the present embodiment, the access of the smart device 180 to the network is achieved by obtaining the identifications of the smart device 180 and wireless access point via the terminal 120 and then sending them to the server 140, and achieving the connection between the smart device 180 and wireless access point 160 via the server. Thus, the present disclosure can solve the problem relating to the limitation to the application of the methods for wireless network access and lack of feasibility and versatility and provide a simplified method for linking the smart device to network with enhanced feasibility and versatility.

Meanwhile, as the more preferable embodiment over the ones as shown in FIGS. 3 and 4, the method for network access provided by the present embodiment provides two different method for reading the identifications of the wireless access point and smart device at terminal side, which improves the feasibility of the method for network access provided by the present embodiment. Furthermore, the server verifies the identity of the wireless access point before delivery of information between the server and the wireless access point such that the security of the method for network access is enhanced. Furthermore, the information transfer among the smart device, wireless access point and server can be encrypted and the information can be message-digested before sending, thereby improving the security and conciseness of the information transfer.

To illustrate more specifically, for example, User 1 turns on the cell phone provided with WeChat application program and then scans the machine-readable codes of a router and a intelligent light printed on the device packages in sequence within the prescribed threshold value. The machine-readable code of the router carries the identification of the router. Similarly, the two-machine-readable of the light carries the identification of the light. User 1 sends the identifications of the router and the intelligent light to the WeChat server by using cell phone simultaneously. After verifying that the two identifications are registered in the WeChat server side, the identification of the intelligent light is sent to the router. Meanwhile, the intelligent light after obtaining gateway address of the router through SSID2 of the router sends its own identification to the router. After successfully verifying the identifications received from the WeChat server by the server and the intelligent light, the router sends the access password to the intelligent light. After receiving the access password, the intelligent light accesses the wireless network provided by the router through SSID1 according to the access password. User 1 only needs to scan the machine-readable codes of router and intelligent light to achieve the wireless network access of intelligent light.

In another specific example, for example, User 2 initiates the intelligent family function added in the WeChat program with interface for scanning machine-readable code after turning on the cell phone provided with the WeChat application program. User 2 scans the machine-readable code of the router in the router's package following the instructions. After scanning, the interface of “My Family” is present. The WeChat account registered in WeChat program by User 2 and the identification of the router are sent to the WeChat server, and then the WeChat server saves the User 2's WeChat account and the identification of the router and binds both of them together. After a period of time, User 2 bought an intelligent TV. She initiates the WeChat application program and then enters into the interface of “My Family” and selects to add device, such that the interface for scanning machine-readable code is present. User 2 scans the machine-readable code of the intelligent TV printed on the label which located on the housing of the TV following the instructions. After scanning, the intelligent TV could be linked to the wireless network provided by the router. In other words, after scanning the machine-readable code of the intelligent TV, User 2's WeChat account registered in the WeChat application program and the identification of the intelligent TV are sent to the WeChat server by the WeChat application program. The WeChat server reads the identification of the router from the binding relationship between pre-registered User 2's account and the identification of the router according to User 2's WeChat account and then associates the router with the intelligent TV. The WeChat server sends the access password of the router to the intelligent TV after successfully verifying the identity of the router and intelligent TV. The intelligent TV accesses the wireless network according to the access password of the router. Further, if User 2 would like to add other smart device such as intelligent light, she merely needs to initiate WeChat application program and enters into interface of “My Family” and then select to add device. The intelligent light could obtain the access password and link to wireless network similar to the aforesaid method for adding the intelligent TV.
